IMPROVEMENT IN SPINNING-RINGS.

Specification forming part of Letters Patent No. 144,004, dated October28, 1.873; application filed September 24, 1873.

To all whom it may concern:

Beit known that I, J osnrn W. WATTLEs, of Canton, of the county ofNorfolk and State of Massachusetts, have invented a new and usefulImprovement in Rings for Ring and Traveler Spinning-Machines; and dohereby declare the same to be fully described in the followingspecification and represented in the accompanying drawings, of which-Figure l is a top view, Fig. 2 an elevation, and Fig. 3 a transversesection, of one of my improved rings.

The said ring has a circular projection elevated 011 its race, suchprojection being to sustain the traveler at its middle or crown. Theinner edge of the projection is curved transversely down to the inneredge of the race, such curve being the arc of ninety degrees of acircle, or thereabont, and there is made in the curved inner edge of theprojection one or more mote or nnb freeing recesses or notches. Each ofsuch notches I sometimes form with a hole leading out of it, or with aVshoulder or abutment at or near one end of it, in order that, whenstruck by a mote or nub or projection from the thread, such shoulder orhole may serve to detach or remove the mote, nnb, or projection from thethread. The recess or notch, however, without such a shoulder or hole,will generally suffice to free the thread from the extraneous matter,mote, or nnb. The raised projection serves to prevent the traveler fromdropping upon the race, or holds the traveler up, so as to enable thethread to be readily passed through it, and thus saves the necessity offirst lifting the traveler off the race in order to effect the threadingof the traveler.

In the drawings, a denotes the race, and b vthe circular projectionraised on such race.

The outer side of the projection stands ver tically, or about so, andmakes a right or slightly obtuse angle with the top of the race. Theinner face c of the projection is curved transversely from the top ofthe projection down to the inner edge t of the race, the curve beingthat of a quadrant of a circle, or approximately such.

This curved inner face of the projection is the surface against whichthe thread is borne by the traveler under the centrifugal forcegenerated in the latter while it is in rapid revolution about the race.Such action of the traveler and the bearing-surface c is found to behighly benecial in producing friction to facilitate the taking up of theyarn by the bobbin.

The mote or nnb freeing recesses in thc bearing-surface c are shown at cc.

The transverse curve of the bearing-surface c should conform, as nearlyas possible, to the curve of that part of` the traveler which is to runnext to it. The recess or recesses serve also to allow the larger motesto be drawn with the yarn through the traveler, thereby preventing suchfrom clogging the traveler or stopping its proper action. The greaterbearing which the raised projection imparts to the traveler preventsboth the traveler and the ring from wearing so fast as with a iiat race.Furthermore, with my improved ring', little or no'waste will collect onthe traveler, and litt-le if any will be thrown upon the ring-rail, thetraveler and rail being kept comparatively clean.

I claim as my invention as follows, viz:

l. A spinning-ring having its circular projection b made or providedwith the curved bearing-surface c, as described, extending from the topof the projection to the inner edge of the race c, and to operate inconnection with a traveler, as set forth.

2. A spinning-ring made or provided with the travelersupportingprojection b and the curved bearing-surface c, and with one or morerecesses, e, arranged in the latter, all being and operatingsubstantially as specified. j
